Portulaca plant named ‘LAZPRT1505’

ABSTRACT

A new and distinct cultivar of  Portulaca  plant named ‘LAZPRT1505’, characterized by its semi-upright to spreading growth habit; vigorous growth habit; freely branching habit; freely flowering habit; fully double dark yellow and orange-colored flowers; and excellent garden performance.

Botanical designation: Portulaca umbraticola Kunth.

Cultivar denomination: ‘LAZPRT1505’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Portulaca plant, botanically known as Portulaca umbraticola Kunth, commonly known as Wingpod Purslanc, and hereinafter referred to by the name ‘LAZPRT1505’.

The new Portulaca plant is a product of a planned breeding program conducted by the Inventor in Merano, South Tyrol, Italy. The objective of the breeding program is to create new vigorous and freely branching Portulaca plants with numerous fully double flowers.

The new Portulaca plant is a naturally-occurring whole plant mutation of a proprietary selection of Portulaca umbraticola Kunth identified as code number IV/8-A, not patented. The new Portulaca plant was discovered and selected by the Inventor as a flowering plant from within a population of plants of the parent selection in a controlled greenhouse environment in Merano, South Tyrol, Italy during the spring of 2014.

Asexual reproduction of the new Portulaca plant cuttings in a controlled greenhouse environment in Merano, South Tyrol, Italy since the spring of 2014, has shown that the unique features of this new Portulaca plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Portulaca have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LAZPRT1505’. These characteristics in combination distinguish ‘LAZPRT1505’ as a new and distinct Portulaca plant:

-   -   1. Semi-upright to spreading growth habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Freely flowering habit.     -   5. Fully double dark yellow and orange-colored flowers.     -   6. Excellent garden performance.

Plants of the new Portulaca can be compared to plants of the parent selection. Plants of the new Portulaca differ primarily from plants of the parent selection in flower color as plants of the parent selection have less intense yellow orange-colored flowers.

Plants of the new Portulaca can be compared to plants of Portulaca oleracea ‘Dynamite Orange’, not patented. In side-by-side comparisons, plants of the new Portulaca differ primarily from plants of ‘Dynamite Orange’ in the following characteristics:

-   -   1. Flowers of plants of the new Portulaca are more fully double         with more petaloids per flower than flowers of plants of         ‘Dynamite Orange’.     -   2. Petaloids of plants of the new Portulaca are narrower and         flatter than petaloids of plants of ‘Dynamite Orange’.     -   3. Plants of the new Portulaca and ‘Dynamite Orange’ differ in         petal and petaloid color as plants of ‘Dynamite Orange’ have         yellowish orange-colored petals and petaloids with         orange-colored stripes.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Portulaca plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Portulaca plant. The photograph comprises a side perspective view of a typical flowering plant of ‘LAZPRT1505’ grown in an outdoor nursery.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in an outdoor nursery in Merano, South Tyrol, Italy and under cultural practices typical of commercial Portulaca production. During the production of the plants, day and night temperatures ranged from 13.8° C. to 28.6° C. and light levels ranged from 60 to 70 klux. Plants were four months old when the photograph and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
